+Git v2.4.2 Release Notes
+========================
+
+Fixes since v2.4.1
+------------------
+
+ * "git rev-list --objects $old --not --all" to see if everything that
+ is reachable from $old is already connected to the existing refs
+ was very inefficient.
+
+ * "hash-object --literally" introduced in v2.2 was not prepared to
+ take a really long object type name.
+
+ * "git rebase --quiet" was not quite quiet when there is nothing to
+ do.
+
+ * The completion for "log --decorate=" parameter value was incorrect.
+
+ * "filter-branch" corrupted commit log message that ends with an
+ incomplete line on platforms with some "sed" implementations that
+ munge such a line. Work it around by avoiding to use "sed".
+
+ * "git daemon" fails to build from the source under NO_IPV6
+ configuration (regression in 2.4).
+
+ * "git stash pop/apply" forgot to make sure that not just the working
+ tree is clean but also the index is clean. The latter is important
+ as a stash application can conflict and the index will be used for
+ conflict resolution.
+
+ * We have prepended $GIT_EXEC_PATH and the path "git" is installed in
+ (typically "/usr/bin") to $PATH when invoking subprograms and hooks
+ for almost eternity, but the original use case the latter tried to
+ support was semi-bogus (i.e. install git to /opt/foo/git and run it
+ without having /opt/foo on $PATH), and more importantly it has
+ become less and less relevant as Git grew more mainstream (i.e. the
+ users would _want_ to have it on their $PATH). Stop prepending the
+ path in which "git" is installed to users' $PATH, as that would
+ interfere the command search order people depend on (e.g. they may
+ not like versions of programs that are unrelated to Git in /usr/bin
+ and want to override them by having different ones in /usr/local/bin
+ and have the latter directory earlier in their $PATH).
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.4.3 Release Notes
+========================
+
+Fixes since v2.4.3
+------------------
+
+ * Error messages from "git branch" called remote-tracking branches as
+ "remote branches".
+
+ * "git rerere forget" in a repository without rerere enabled gave a
+ cryptic error message; it should be a silent no-op instead.
+
+ * "git pull --log" and "git pull --no-log" worked as expected, but
+ "git pull --log=20" did not.
+
+ * The pull.ff configuration was supposed to override the merge.ff
+ configuration, but it didn't.
+
+ * The code to read pack-bitmap wanted to allocate a few hundred
+ pointers to a structure, but by mistake allocated and leaked memory
+ enough to hold that many actual structures. Correct the allocation
+ size and also have it on stack, as it is small enough.
+
+ * Various documentation mark-up fixes to make the output more
+ consistent in general and also make AsciiDoctor (an alternative
+ formatter) happier.
+
+ * "git bundle verify" did not diagnose extra parameters on the
+ command line.
+
+ * Multi-ref transaction support we merged a few releases ago
+ unnecessarily kept many file descriptors open, risking to fail with
+ resource exhaustion.
+
+ * The ref API did not handle cases where 'refs/heads/xyzzy/frotz' is
+ removed at the same time as 'refs/heads/xyzzy' is added (or vice
+ versa) very well.
+
+ * The "log --decorate" enhancement in Git 2.4 that shows the commit
+ at the tip of the current branch e.g. "HEAD -> master", did not
+ work with --decorate=full.
+
+ * There was a commented-out (instead of being marked to expect
+ failure) test that documented a breakage that was fixed since the
+ test was written; turn it into a proper test.
+
+ * core.excludesfile (defaulting to $XDG_HOME/git/ignore) is supposed
+ to be overridden by repository-specific .git/info/exclude file, but
+ the order was swapped from the beginning. This belatedly fixes it.
+
+ * The connection initiation code for "ssh" transport tried to absorb
+ differences between the stock "ssh" and Putty-supplied "plink" and
+ its derivatives, but the logic to tell that we are using "plink"
+ variants were too loose and falsely triggered when "plink" appeared
+ anywhere in the path (e.g. "/home/me/bin/uplink/ssh").
+
+ * "git rebase -i" moved the "current" command from "todo" to "done" a
+ bit too prematurely, losing a step when a "pick" did not even start.
+
+ * "git add -e" did not allow the user to abort the operation by
+ killing the editor.
+
+ * Git 2.4 broke setting verbosity and progress levels on "git clone"
+ with native transports.
+
+ * Some time ago, "git blame" (incorrectly) lost the convert_to_git()
+ call when synthesizing a fake "tip" commit that represents the
+ state in the working tree, which broke folks who record the history
+ with LF line ending to make their project portabile across
+ platforms while terminating lines in their working tree files with
+ CRLF for their platform.
+
+ * Code clean-up for xdg configuration path support.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.
UI, Workflows & Features
+ * The bash completion script (in contrib/) learned a few options that
+ "git revert" takes.
+
+ * Whitespace breakages in deleted and context lines can also be
+ painted in the output of "git diff" and friends with the new
+ --ws-error-highlight option.
+
+ * List of commands shown by "git help" are grouped along the workflow
+ elements to help early learners.

* "git p4" now detects the filetype (e.g. binary) correctly even when
the files are opened exclusively.
chunks from Perforce, instead of making one call to "p4 changes"
that may trigger "too many rows scanned" error from Perforce.
+ * Unlike "$EDITOR" and "$GIT_EDITOR" that can hold the path to the
+ command and initial options (e.g. "/path/to/emacs -nw"), 'git p4'
+ did not let the shell interpolate the contents of the environment
+ variable that name the editor "$P4EDITOR" (and "$EDITOR", too).
+ This release makes it in line with the rest of Git, as well as with
+ Perforce.
+
+ * A new short-hand <branch>@{push} denotes the remote-tracking branch
+ that tracks the branch at the remote the <branch> would be pushed
+ to.
+
* "git show-branch --topics HEAD" (with no other arguments) did not
do anything interesting. Instead, contrast the given revision
against all the local branches by default.
* The Git subcommand completion (in contrib/) listed credential
helpers among candidates, which is not something the end user would
- invoke interatively.
+ invoke interactively.
+
+ * The index file can be taught with "update-index --untracked-cache"
+ to optionally remember already seen untracked files, in order to
+ speed up "git status" in a working tree with tons of cruft.
+
+ * "git mergetool" learned to drive WinMerge as a backend.
+
+ * "git upload-pack" that serves "git fetch" can be told to serve
+ commits that are not at the tip of any ref, as long as they are
+ reachable from a ref, with uploadpack.allowReachableSHA1InWant
+ configuration variable.
+
+ * "git cat-file --batch(-check)" learned the "--follow-symlinks"
+ option that follows an in-tree symbolic link when asked about an
+ object via extended SHA-1 syntax, e.g. HEAD:RelNotes that points at
+ Documentation/RelNotes/2.5.0.txt. With the new option, the command
+ behaves as if HEAD:Documentation/RelNotes/2.5.0.txt was given as
+ input instead.

'git cat-file' (-t [--allow-unknown-type]| -s [--allow-unknown-type]| -e | -p | <type> | --textconv ) <object>
-'git cat-file' (--batch | --batch-check) < <list-of-objects>
+'git cat-file' (--batch | --batch-check) [--follow-symlinks] < <list-of-objects>
DESCRIPTION
-----------
--allow-unknown-type::
Allow -s or -t to query broken/corrupt objects of unknown type.
+--follow-symlinks::
+ With --batch or --batch-check, follow symlinks inside the
+ repository when requesting objects with extended SHA-1
+ expressions of the form tree-ish:path-in-tree. Instead of
+ providing output about the link itself, provide output about
+ the linked-to object. If a symlink points outside the
+ tree-ish (e.g. a link to /foo or a root-level link to ../foo),
+ the portion of the link which is outside the tree will be
+ printed.
++
+This option does not (currently) work correctly when an object in the
+index is specified (e.g. `:link` instead of `HEAD:link`) rather than
+one in the tree.
++
+This option cannot (currently) be used unless `--batch` or
+`--batch-check` is used.
++
+For example, consider a git repository containing:
++
+--
+ f: a file containing "hello\n"
+ link: a symlink to f
+ dir/link: a symlink to ../f
+ plink: a symlink to ../f
+ alink: a symlink to /etc/passwd
+--
++
+For a regular file `f`, `echo HEAD:f | git cat-file --batch` would print
++
+--
+ ce013625030ba8dba906f756967f9e9ca394464a blob 6
+--
++
+And `echo HEAD:link | git cat-file --batch --follow-symlinks` would
+print the same thing, as would `HEAD:dir/link`, as they both point at
+`HEAD:f`.
++
+Without `--follow-symlinks`, these would print data about the symlink
+itself. In the case of `HEAD:link`, you would see
++
+--
+ 4d1ae35ba2c8ec712fa2a379db44ad639ca277bd blob 1
+--
++
+Both `plink` and `alink` point outside the tree, so they would
+respectively print:
++
+--
+ symlink 4
+ ../f
+
+ symlink 11
+ /etc/passwd
+--
+
+
OUTPUT
------
If '-t' is specified, one of the <type>.
<object> SP missing LF
------------
+If --follow-symlinks is used, and a symlink in the repository points
+outside the repository, then `cat-file` will ignore any custom format
+and print:
+
+------------
+symlink SP <size> LF
+<symlink> LF
+------------
+
+The symlink will either be absolute (beginning with a /), or relative
+to the tree root. For instance, if dir/link points to ../../foo, then
+<symlink> will be ../foo. <size> is the size of the symlink in bytes.
+
+If --follow-symlinks is used, the following error messages will be
+displayed:
+
+------------
+<object> SP missing LF
+------------
+is printed when the initial symlink requested does not exist.
+
+------------
+dangling SP <size> LF
+<object> LF
+------------
+is printed when the initial symlink exists, but something that
+it (transitive-of) points to does not.
+
+------------
+loop SP <size> LF
+<object> LF
+------------
+is printed for symlink loops (or any symlinks that
+require more than 40 link resolutions to resolve).
+
+------------
+notdir SP <size> LF
+<object> LF
+------------
+is printed when, during symlink resolution, a file is used as a
+directory name.

DESCRIPTION
-----------
-Submodules allow foreign repositories to be embedded within
-a dedicated subdirectory of the source tree, always pointed
-at a particular commit.
+Inspects, updates and manages submodules.
-They are not to be confused with remotes, which are meant mainly
-for branches of the same project; submodules are meant for
-different projects you would like to make part of your source tree,
-while the history of the two projects still stays completely
-independent and you cannot modify the contents of the submodule
-from within the main project.
-If you want to merge the project histories and want to treat the
-aggregated whole as a single project from then on, you may want to
-add a remote for the other project and use the 'subtree' merge strategy,
-instead of treating the other project as a submodule. Directories
-that come from both projects can be cloned and checked out as a whole
-if you choose to go that route.
+A submodule allows you to keep another Git repository in a subdirectory
+of your repository. The other repository has its own history, which does not
+interfere with the history of the current repository. This can be used to
+have external dependencies such as third party libraries for example.
+
+When cloning or pulling a repository containing submodules however,
+these will not be checked out by default; the 'init' and 'update'
+subcommands will maintain submodules checked out and at
+appropriate revision in your working tree.
Submodules are composed from a so-called `gitlink` tree entry
in the main repository that refers to a particular commit object
The logical name can be used for overriding this URL within your
local repository configuration (see 'submodule init').
-This command will manage the tree entries and contents of the
-gitmodules file for you, as well as inspect the status of your
-submodules and update them.
-When adding a new submodule to the tree, the 'add' subcommand
-is to be used. However, when pulling a tree containing submodules,
-these will not be checked out by default;
-the 'init' and 'update' subcommands will maintain submodules
-checked out and at appropriate revision in your working tree.
-You can briefly inspect the up-to-date status of your submodules
-using the 'status' subcommand and get a detailed overview of the
-difference between the index and checkouts using the 'summary'
-subcommand.

COMMANDS
--------

indexes that take a significant amount of time to read or write.
+--untracked-cache::
+--no-untracked-cache::
+ Enable or disable untracked cache extension. This could speed
+ up for commands that involve determining untracked files such
+ as `git status`. The underlying operating system and file
+ system must change `st_mtime` field of a directory if files
+ are added or deleted in that directory.
+
+--force-untracked-cache::
+ For safety, `--untracked-cache` performs tests on the working
+ directory to make sure untracked cache can be used. These
+ tests can take a few seconds. `--force-untracked-cache` can be
+ used to skip the tests.

is created by giving the `--depth` option to linkgit:git-clone[1], and
its history can be later deepened with linkgit:git-fetch[1].

+ A <<def_repository,repository>> that holds the history of a

+
+[[def_superproject]]superproject::
+ A <<def_repository,repository>> that references repositories

+ The superproject knows about the names of (but does not hold

[[def_symref]]symref::
Symbolic reference: instead of containing the <<def_SHA1,SHA-1>>
id itself, it is of the format 'ref: refs/some/thing' and when
that categorizes commands by type, so they can be listed in appropriate
subsections in the documentation's summary command list. Add an entry
for yours. To understand the categories, look at git-commands.txt

+
`branch.<name>.merge`). A missing branchname defaults to the
current one.
+'<branchname>@\{push\}', e.g. 'master@\{push\}', '@\{push\}'::
+ The suffix '@\{push}' reports the branch "where we would push to" if
+ `git push` were run while `branchname` was checked out (or the current
+ 'HEAD' if no branchname is specified). Since our push destination is
+ in a remote repository, of course, we report the local tracking branch
+ that corresponds to that branch (i.e., something in 'refs/remotes/').
++
+Here's an example to make it more clear:
++
+------------------------------
+$ git config push.default current
+$ git config remote.pushdefault myfork
+$ git checkout -b mybranch origin/master
+
+$ git rev-parse --symbolic-full-name @{upstream}
+refs/remotes/origin/master
+
+$ git rev-parse --symbolic-full-name @{push}
+refs/remotes/myfork/mybranch
+------------------------------
++
+Note in the example that we set up a triangular workflow, where we pull
+from one location and push to another. In a non-triangular workflow,
+'@\{push}' is the same as '@\{upstream}', and there is no need for it.
+
'<rev>{caret}', e.g. 'HEAD{caret}, v1.5.1{caret}0'::
A suffix '{caret}' to a revision parameter means the first parent of
that commit object. '{caret}<n>' means the <n>th parent (i.e.
callback function for every ref. The callback function has this

+== Untracked cache
+
+ Untracked cache saves the untracked file list and necessary data to
+ verify the cache. The signature for this extension is { 'U', 'N',
+ 'T', 'R' }.
+
+ The extension starts with
+
+ - A sequence of NUL-terminated strings, preceded by the size of the
+ sequence in variable width encoding. Each string describes the
+ environment where the cache can be used.
+
+ - Stat data of $GIT_DIR/info/exclude. See "Index entry" section from
+ ctime field until "file size".
+
+ - Stat data of core.excludesfile
+
+ - 32-bit dir_flags (see struct dir_struct)
+
+ - 160-bit SHA-1 of $GIT_DIR/info/exclude. Null SHA-1 means the file
+ does not exist.
+
+ - 160-bit SHA-1 of core.excludesfile. Null SHA-1 means the file does
+ not exist.
+
+ - NUL-terminated string of per-dir exclude file name. This usually
+ is ".gitignore".
+
+ - The number of following directory blocks, variable width
+ encoding. If this number is zero, the extension ends here with a
+ following NUL.
+
+ - A number of directory blocks in depth-first-search order, each
+ consists of
+
+ - The number of untracked entries, variable width encoding.
+
+ - The number of sub-directory blocks, variable width encoding.
+
+ - The directory name terminated by NUL.
+
+ - A number of untrached file/dir names terminated by NUL.
+
+The remaining data of each directory block is grouped by type:
+
+ - An ewah bitmap, the n-th bit marks whether the n-th directory has
+ valid untracked cache entries.
+
+ - An ewah bitmap, the n-th bit records "check-only" bit of
+ read_directory_recursive() for the n-th directory.
+
+ - An ewah bitmap, the n-th bit indicates whether SHA-1 and stat data
+ is valid for the n-th directory and exists in the next data.
+
+ - An array of stat data. The n-th data corresponds with the n-th
+ "one" bit in the previous ewah bitmap.
+
+ - An array of SHA-1. The n-th SHA-1 corresponds with the n-th "one" bit
+ in the previous ewah bitmap.
+
+ - One NUL.
